Plastic straws are already a thing of the past in cities like San Francisco and Seattle, which have adopted legislation that bans restaurants and bars from giving the utensils to customers.

While has already gone into effect, San Francisco will in July – just six months after the state of California from serving plastic straws.

From now on, if a customer in California wants to sip their soda or coffee out of a plastic straw, they‘ll have to ask – or use an alternative.

Loliware‘s seaweed straws biodegrade in a matter of weeks.Loliware

Starting this summer, edible bioplastics company Loliware will begin rolling out seaweed straws at hotel chains like Marriott and like Pernod Ricard. At the end of the year, they‘ll launch a product designed specifically for juice boxes. By the start of 2020, they‘ll begin offering small packs of straws for consumer purchase.

For the co-founder and CEO of Loliware, Chelsea Briganti, plastic straw bans are a “gateway” to raising awareness about the dangers of plastic waste.

In the US, around a day wind up in landfills or in the ocean- enough straws to wrap around the earth two-and-a-half times. A from Science Advances found that only 9% of the world‘s plastic waste is recycled, while around 12% is incinerated. The remaining 79% accumulates in landfills or the environment.

As plastic cups, utensils, containers, and packages make their way into nature, they can take around , endangering wildlife such as birds and marine animals.

As someone who grew up surfing in Hawaii, Briganti recognized that plastic alternatives were a way to preserve marine life. In 2015, she launched Loliware with co-founder Leigh Ann Tucker.

The company‘s first product was an edible cup that appeared on Shark Tank, but (people complained that or tough). Though the seaweed straw has a similar concept, Briganti said customers should think of it as a “guilt-free” alternative to plastic rather than something to devour.

“It can be eaten, but this is not a food per se, or a snack,” she said. “Don‘t expect to eat your whole straw as if it‘s a candy.”

Though Loliware isn‘t the first company to ppropose an compostable alternative to plastic straws, Briganti said seaweed functions better than paper, which can . Another popular substitute, straws made from polylactic acid (PLA) derived from corn starch or sugar cane, requires and essentially in the environment.

Loliware‘s sustainability adviser, Daniela Saltzman, said their straw “looks, feels, and acts like plastic,” while Briganti said it has a “neutral” taste that‘s not salty like traditional seaweed.

Since the straws come without a label, it‘s likely that customers won‘t even know they‘re consuming something different, Briganti said.

After 18 hours of use, the straw will become soft and begin to “disappear,” but it won‘t fully biodegrade until it‘s composted – or in the unfortunate event that it winds up as litter.

“We‘re not advocating [that] people throw Loliware straws into the ocean,” said Briganti, “but if one ends up there by accident, it breaks down in a matter of weeks without any negative impacts on marine animals.”
